On a BA flight from London to Singapore, there would be roughly 368 litres of fart expelled into the air

Jacob Rosenberg, a clinical professor at the University of Copenhagen, made the discovery after noticing that his stomach (dạ dày) had bloated (phồng lên, sưng lên, phù lên) on a long-haul flight to New Zealand.

After clocking that his empty water bottle had expanded (nở ra, phồng ra) during the flight, then crumpled (bị ép thành nhiều nếp, hoặc vò nhau) when it came back down to earth, he realised that the same could apply to his stomach. He told the BBC: “The pressure drops and the air must expand into more space.” According to Jacob, the gas sitting inside the stomach then expands by 30 per cent… and it needs to go somewhere.

...The average person lets out between 0.5 and 1.5 litres of fart a day according to Kyle Staller, M.D., a gastroenterologist (bác sĩ chuyên khoa dạ dày-ruột) at Massachusetts General Hospital.
